Abstract

The application discloses a method and device for processing multimedia files. For a multimedia file to be processed, its payload data is obtained, and the payload data includes multi-frame data composing the multimedia file; several frame data are selected as the frame data to be encrypted, And encrypt the frame data to be encrypted, and set the encryption flag in the frame header of the encrypted frame data, and form the new payload data from the encrypted frame data and the unencrypted frame data; perform frame-level processing on the new payload data Encoding to obtain the numbered multimedia file. For the multimedia files provided by this application, users can only decrypt and play the lossless files if they have the decryption authority of the multimedia files. Therefore, even if the user with the decryption authority transmits the downloaded multimedia files to other users, if other users do not have the multimedia file Decryption authority, it still cannot play lossless files, which realizes the protection of the copyright of multimedia files.

Description

technical field [0001] The present application relates to the field of multimedia technologies, and more specifically, to a method and device for processing multimedia files. Background technique [0002] With the development of mobile Internet technology, more and more multimedia content providers are publishing and selling high-quality multimedia information through the Internet. However, due to the uncontrollability of the Internet and the lossless copying and dissemination of digital media, it is very difficult to protect the copyright of digital multimedia information.
